Vedclass · Answer

(A) The acidic strength of a species is determined by its ability to donate a proton $(H^+)$. Stronger acids have weaker conjugate bases. Comparing the conjugate bases: $NH_3$ (from $NH_4^+$),$OH^-$ (from $H_2O$),$H_2O$ (from $H_3O^+$),$F^-$ (from $HF$),and $O^{2-}$ (from $OH^-$). The basic strength order of these conjugate bases is $O^{2-} > NH_3 > OH^- > F^- > H_2O$. Therefore,the acidic strength order is the reverse: $OH^- < H_2O < NH_4^+ < HF < H_3O^+$.

Arrange $NH_4^+$,$H_2O$,$H_3O^+$,$HF$,and $OH^-$ in increasing order of their acidic strength.
